I had our first motor home rust proofed with Ziebart. It was a black wax-like material they sprayed on everything steel. Aside from the mess, I had three issues with the warranty, process and material.
1) To maintain the warranty, they required I return annually for touch-up, hence I always dealt with a mess. After the 3rd return visit, I stopped going back. I wondered about the extra thick build-up of black stuff applied over a dirty chassis.
2) They drilled holes in lots of places, then plugged the holes with plastic caps. That bothered me.
3) After about 15 years, the extra thick black build-up dried & cracked, then curled looking like potato chips hanging on the frame and elsewhere. This caused moisture to collect in places that would otherwise dry quickly.
So in the end, I felt the product did more harm than good. I would never rust proof another vehicle. Also considering the issues it causes with repair & replacement of some parts. The stuff makes working in the area a miserable task....speaking from first-hand experience.
I have no opinion with the other options.
